Almost all processes containing water have a need for pH measurement. The pH of wastewater leaving manufacturing plants and wastewater purification plants, as well as potable water from municipal drinking water plants, must be within a specific pH "window" as set forth by local, state, or federal regulatory agencies. By Frederick J. Kohlmann

Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.

The City of Palm Coast, FL was experiencing elevated color in the concentrate stream being directed to the lime softening facility to recover as drinking water. In an effort to meet secondary color standards at the lime plant, this water quality issue limited the volume of the concentrate able to be recovered.

A wastewater authority in Pennsylvania reached an $82 million deal with the federal government after it allegedly released eight million gallons of raw sewage into the Susquehanna River and Paxton Creek over six years.

Today, due to the multitude of organics, the organic contamination of wastewater cannot be defined with passable analytical effort. Therefore, composite parameters become more important for the description of organic contamination. Parameters have been defined to enable a fast detection of organic loads.

There’s no denying that conversations are readily available on all types of “costs” of addressing the global water crisis: the cost to the environment; the cost to be paid by future generations; the costs of not keeping on top of water infrastructure maintenance and reinforcement; the cost to private households, etc.

Many utilities are moving to a traditional business mindset rather than continuing as largely compliance-driven entities. This is challenging leaders to apply asset management and smart infrastructure strategies, to become more programmatic in managing water, and to consider the big picture in addressing public needs.

Facing state Department of Environmental Quality mandates, an Arizona wastewater treatment plant (WWTP) took on a large-scale expansion project and effluent-quality upgrade to become a state-of-the-art water reclamation facility.

Water scarcity is becoming more and more in focus these days as California enters into the fourth consecutive year of a historic drought, and even as torrential rains pelted the bay area recently, the Sierra’s snow pack, which is a key source of water for the region, is far below the seasonal average.

As global conditions place more stress on water resources, a great deal of attention is being paid to water reuse technologies, particularly those that facilitate the reuse of the next level of difficult-to-treat or highly variable raw water sources.

Horizon City is located in El Paso County, the most western county in Texas. The city is home to a rapidly growing population of 19,000 people, up from 5,000 during the 2000 Census. The City takes its name from the real estate development company, the Horizon City Corporation. With less than 9 inches of annual rainfall, water conservancy is a routine way of life in this part of the State.

The Trail Lakes Hatchery is owned by the State of Alaska and is managed under contract by the Cook Inlet Aquaculture Association (CIAA) on behalf of the Alaska Department of Fish and Game. CIAA was established in 1976 to provide the Cook Inlet drainage with an organized and reliable salmon stock. The Trail Lakes facility is permitted to introduce sockeye and coho salmon at several sites throughout the Cook Inlet watershed.

A CSX-owned train carrying millions of pounds of crude oil derailed and exploded Monday afternoon in West Virginia, leaking its contents near the Kanawha River, a drinking water source for two counties.

LiqTech International, Inc. (NYSE MKT: LIQT) ("LiqTech") is pleased to announce that it has received the first pilot order for a newly developed in-well situated ground water treatment system from the leading pump producer, Grundfos.

Flowrox, a global leader in heavy-duty industrial valve manufacturing and services, is announcing the launch of the Flowrox Expulse™ product, designed to assist during pump and dampener maintenance by reducing noise and vibration associated with traditional methods—which can lead to pipe damage that can cause breakage and a loss of revenue.

The International Society of Automation (ISA) recently announces the opening of registration for its 2015 Analysis Division Symposium, which will explore the latest advances in analytical processes, techniques, and applications 26-30 April 2015 in Galveston, Texas, USA.

IDModeling, Inc., a leading global provider of smart water network software and services, is deploying its flagship smart water enterprise software, Sedaru, for the City of Santa Ana Public Works Agency (City).

Agriculture Secretary Tom Vilsack recently announced that the U.S. Department of Agriculture is accepting public comments on its interim final rule for the new Agricultural Conservation Easement Program (ACEP), designed to help producers protect working agricultural lands and wetlands.

Agriculture Secretary Tom Vilsack announced recently that USDA’s Natural Resources Conservation Service will invest an additional $84M through the Emergency Watershed Protection Program (EWP) to help disaster recovery efforts through more than 150 projects in 13 states.

Over the past several decades, activated carbon has proven to be a reliable, cost-effective technology for the control of various odorous compounds (hydrogen sulfide, mercaptans, methyl sulfide compounds, and other VOC) at municipal wastewater treatment plants. Furthermore, as the needs of the market have changed, activated carbon technology has also changed, with numerous types of carbons emerging over the years for odor control. Learn more about Jacobi Carbons’ full range of activated carbons for municipal odor control.

Mainsail Global’s Boone diffuser membranes are designed for the petro-chemical market with hydrogenated acrylonitrile-butadiene rubber (HNBR). These custom membranes are built for durability, and can withstand long-term exposure to heat, oil and chemicals readily present in petro-chemical wastewater streams. With excellent tensile strength, abrasion and ozone resistance and higher modulus retention at elevated temperatures, Boone membranes combine the physical strength and chemical makeup of HNBR for an ideal solution in petro-chemical wastewater treatment.
